To all whom t may concern.'

Be it known that I, AUGUST SCHIFFERS, manufacturer, a subject of the King of Prussia', residing at No. 15 Eilfschornsteinstrasse, Aix-la-Chapelle, in the Kingdom of Prussia, Empire of Germany, have invented certain new and useful Improvements in Machines for Dyeing, Bleaching, and the Like; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention relates to dyeingmachinery and particularly to a machine with the aid of which all kinds of textilefibers such as wool, cotton, and the like can be dyed, bleached etc. not only in state of loosethreifls, or cops, spools, bobbins and so forth, but also in state of finished goods.

By means of this new machine the dyeing, bleaching etc. of'teXtile-iibers or goods in any state or form cannot only be accomplished quicker and better than it has been possible to do with any machines hitherto employed for this purpose, but also all the different manipulations necessary to obtain the desired end in View, as for instance cen-- trifuging, fixing, rinsing and d rying of the fibers or goods can be executed 1n succession without necessitating removing the latter Vfrom the dye-vat and repacking them.

By means of this improvement the advantage is gained, that the working operation can be' executed quickly, with ease, and 1n an absolutely safe manner, whereby not only time and money are saved, but also the Wear and tear of the machine, particularly the dye-vat and its armature, are reduced to a minimum. v

In the accompanying drawings Figure l is-a vertical sectional view illustrating one embodiment of my invention, with the parts in one position. Fig. 2 is view similar to Fig. 1, showing the parts 1n another position. Fig.3 is a horizontal sectional view showing a detail of an improved adjusting means, formingv one of the features of my invention. I Thedye-vat 1 is provided with a bottomflange 3 adapted to be bolted to a support. The bottom 5 of the dye-vat 1 forms an integral part of the latter, whereas its cover 6 can be raised as Well as swung out to simlify the admission of the raw goods to the dye-vat and the removal of the finished goods therefrom. The cover 6 is provided with a tubular trunnion 7, seated in a sleeve 8 one side 'of which is provided with teeth to form a rack. The sleeve 8 is seated in a tubular lateral projection of the dye-vat 1, and carries upon its top-face bearing-balls 10.in order to minimize friction and thus render the swinging in and out of the cover 6 easy. The trunnion 7 is made airand watertight in the projection 9 by means of the packing 11 which preferably is of the hydraulic kind. The top of the dye-vat is provided with a groove 12 into which the annular feather 13 of the cover 6 enters and yis ground-in therein to make this joint airand water-tight. Eye-bolts 14 are employed to firmly secure the cover G to the dye-vat 1. 'l`hecentering of the cover 6 is simplified by the pintle 15 which enters the eye 16, projecting from said vat, when the cover 6 is lowered. The raising of the latter is accomplished by means of the spur-wheel 17 seated upon the shaft 18 which wheel meshes with the teeth of the sleeve 8. Rotation is imparted to the shaft 18 by means of the hand-wheel 19 rotating the worm 20, which in turn drives, the worm-wheel 21 seated upon the shaft 18, so that on rotatinfr the hand-wheel'19 in the one or the other irection the cover 6 may be raised or lowered.

The boring of the trunnion 7 is continued by the channel 22 of the cover and ends in the center of the latter in the shape of a ringchannel 23. The inner wall of the latter forms a part of the stuing-box 24, the packing-ring 25 of which is held down by the ring 26. The latter can be pressed down by the cap-shaped ring 27 wherein the upper neck-bearing 28 of the main-shaft 29 y1s arranged. The latter carries the annular receiver 3() which may be held in any suitable manner on said shaft removably but not rotatably. The bottom 31 of the receiver 30 is seated upon the conical part 32 of the shaft 29 and opposite the said conical part 32 is situated a perforated spacingring 34 provided with a V-shaped tightening groove into which the correspondingly shaped faces of the ring-channel 23 enter. The ring 34 is threaded to receive the ring 35 whose pintles 3G are destined for the reception of any hoisting-device for removing the receiver and its contents from the dyevat 1. The mantles 37 and 38 of thereceiver are perforated so that the dyeing.- liquor can be driven through the goods from 5. ring 40.

the inside to` the outside of the receiver or in,the reverse way. Below the bottom 5` of the dye-vat 1 the mainl bearing 39 ofthe shaft 29 isarranged,V

which -bearing is provided with a packingressed downward by an annular plate-41 and capable of beingtightened vby means ofthe ring 42, the .pressure of'which is caused and regulated by the cup-shaped ring way 44 of the balls 45 is arranged, which shown) which slide inthe usual manner `in longitudinal slots (likewise not shown) of the friction-sleeve 47. The latter is.l pro-- vided with an annular groove 48into which the pintles 49 of-the forked end of the lever 50 pivot'edtofthehanger 51 enter (Fig. 1). To the free end of thelever 50 arod 52 is hinged whichcarries on its threaded end a hand-wheel 53 the hub of which is rotatably held inthe bracket 54 secured to the ydye'- vat 1, so lthat on rot-ating saidhand-wheel The pulley 55 of the-vmain-shaft 29 is pr`o' vided with a conical face 56 for the corre- 4 in the one or` -in-the other direction. the

friction-sleeve v47- maybe'raised or lowered.

' spondingly shaped lower end of the friction- Vi5 .sleeve 47, so that ongraduauy Pressing the' latter on the conical face 56 the main-.shaft 2 9 can be braked.

" In the hanger 51 the lower neck-bearing l -57 is arranged and provided withlat'eral pintles 58 which are received bythe forked end of-thelever 59, likewiselpivoted to said hanger 51.' -The latter is connected with main-shaft 129 is raised where the-lever 5o by means of the link eo. ,In this -manner the brake-arrangement 47, 56

can be'rendered inoperative when the rod 52' is lowered. Simultaneously) herewith the faces of the vring V34 and the ring-channel 23 are pressed airand water-tight against each oth'er,.so that the d eing-liquor on enterin voyway of the c n nels 22 and 23 will ndi no otherv outlet than through the inner`1nantle37, the goods to be dyed, and

Supposingnowl `that the 'charged receiver has been" inserted and the parts 23 and 34' brought into-contact with each other as indicated above. Since the' two joints are airand water-tighthigh vacuum, absolutely necessary for obtaining a uniform dying of the goods, can'be attainedin the dye-vat- 1,

which vacuum was hitherto obtainable ay `v poor and unsatisfactorymanner only.

Afterthe dyeing-liquor has been removed the goods must be freed fromthe dyeingliquor still cmltained therein to which end 43 upon theinside of which the raceroperated by the y the ground` the main-shaft 29v is lowered to bring the parts 23 and 34 out of contact,'whereupon the shaft 29 is rotated .until no more liquor is thrown oi through the centrifugal action of the receiver. To bring the receiver and the goods contained thereiny to ja standstill the friction-sleeve47 is Vgradually lowered to bring it into braking-contact with the Aconical upper end of the pulley of the a 75 main-shaft 29.

The fixing or oxidizing must be accomplished next, to which end the parts 23 and 34 are brought again into an air-tight contact with` each other whereupon air is passed through the goods contained in the receiver 30. lThis can be accomplished in two dierent ways, namely to drive the cold air through the goods from the center of the receiver' to the periphery of the latter` or vice versa.

As the centrifugating of the goods following the rinsing is executed inthe same way as in the first instance it is deemed superluous to enlarge upon it again here. l

The final manipulation is the drying of the goods, to which end a blower (not shown) presses goods, from the center of the receiver outward ,to the periphery of the latter and then vice versa. To do this in the rst mentioned manner the parts-23 and 34 are brought into contact with each other, so that the cooled and moisture-carrying air passes out through the channel 64. When the hot yair is to enter the goods by way of the outerV mantle 38 the cooled and moisture-charged air passes out by VWa'y of the channels 62.

hot airthrough the dyed The air employed for the drying of the. i

goodsmay loe-heated in any desired manner.

The goods are now dyed as well as dried and in order -to remove them from the dyevat the eye-bolts 14 are unscrewed, the cover 6 is raised by the aid of the lifting-device hand-wheel- 19 and swung out of the way, whereupon' a hoisting-device 'of any suitable kindis connected with the pintles 36andthen the receiver and-its contents are removedv from the dye-vat to be replaced by meantime. The contentsv of the latter are then treated in the samey manner as indianother -receiver filled-in the l cated above, after the cover 6 has been ieplacedand bolted down.
